\section{Tables}\label{sec:1}
\noindent
A simple table:
\begin{table}[!tbh]
    \centering
        \begin{tabular}{|l|l|}
        \hline
        \textbf{Ice Cream Flavor} & \textbf{Count}\\
        \hline
        Chocolate Chips & 2\\
        Butterscotch & 3\\
        Vanilla Blackforest & 1\\
        \hline
        \end{tabular}
    \label{tab:1}
    \caption{\textbf{This is a very simple table}}
\end{table}


\noindent
A table with a row spanning multiple columns:
\begin{table}[!tbh]
    \centering
        \begin{tabular}{|l|l|}
        \hline
        \multicolumn{2}{|c|}{\textbf{IceCream Fest}}\\ %mane 2 ta col eksathe korlo. kono & dey nai
%\multicolumn{num_cols}{alignment}{contents}.
        \hline
        \textbf{Ice Cream Flavor} & \textbf{Count}\\
        \hline
        Chocolate Chips & 2\\
        Butterscotch & 3\\
        Vanilla Blackforest & 1\\
        \hline
        \end{tabular}
    \label{tab:2}
    \caption{\textbf{This is a multicolumn table}}
\end{table}

\noindent
A table with a column spanning multiple rows (needs the multirow package):
\begin{table}[!tbh]
    \centering
        \begin{tabular}{|l|l|l|}
        \hline
        \multirow{2}{*}{Chocolate} & \textbf{Snickers} & \textbf{KitKat}\\ %\multirow{''num_rows''}{''width''}{''contents''} || (* for the width means the content's natural width).

        \cline{2-3} %The \cline command draws horizontal lines across the columns specified, beginning in column i and ending in column j, which are identified in the mandatory argument.
        & 2 & 3\\
        \hline
        \end{tabular}
    \label{tab:3}
    \caption{This is a multirow table}
\end{table}

\begin{table}[ht]
    \caption{Multi-column and multi-row table}
    \begin{center}
        \begin{tabular}{ccc}
            \hline
            \multicolumn{2}{c}{\multirow{2}{*}{Multi-col-row}}&X\\
            \multicolumn{2}{c}{} & X\\
            \hline
            \vline{} X & \vline{} X & \vline{} X\\
            \hline
        \end{tabular}
    \end{center}
    \label{tab:multicol}
\end{table}

\section{Figures}
Figures need graphicx package. We can see the BUET logo in Figure~\ref{fig:buetlogo}.
If you need to draw your own figure either use \textbf{tikz} package,
or use dedicated software to draw images for \LaTeX{} like \textbf{LatexDraw} or \textbf{XFig}.

\begin{figure}[h]
\centering
\includegraphics[width=0.3\textwidth]{buetlogo.png}
\caption{BUET logo.}
\label{fig:buetlogo}
